Recent developments in the climate change arena, including the Paris Agreement in 2015 and the publication of the IPCC Special Report on Global Warming of 1.5 °C, have noted the potential need for negative emission technologies to remove carbon dioxide from the atmosphere in order to limit temperature increase.

In a clear sign of continuing long-term climate change associated with record atmospheric concentrations of greenhouse gases, 2015, 2016, 2017 and 2018 have been confirmed as the four warmest years on record.

World Meteorological Day takes place every year on 23 March and commemorates the coming into force on 23 March 1950 of the Convention establishing the World Meteorological Organization. It showcases...

The ever-growing global population faces a wide range of hazards such as tropical cyclone storm surges, heavy rains, heatwaves, droughts and many more. Long-term climate change is increasing the intensity...

As atmospheric CO 2 continues to increase, more and more CO 2 enters the ocean, which reduces pH (pH is a measure of acidity, the lower the pH, the more acidic the liquid) in a process referred to as ocean acidification. Declines in surface ocean pH due to ocean acidification are already detectable and accelerating.

WMO hosted the first Symposium and User Summit of the Integrated Global Greenhouse Gas Information System (IG3IS), one of the recent initiatives of the WMO Global Atmosphere Watch (GAW) Programme, from 13 to 15 November in Geneva.

The World Meteorological Organization (WMO) and the Green Climate Fund (GCF) have signed a formal agreement to work together to leverage WMO expertise on weather, climate and water to increase effectiveness of GCF funded activities and support low carbon and climate resilient development.

Global CO2 emissions are expected to rise by more than 2% in 2018 because of renewed growth in coal use, and continued growth in oil and gas use, according to the latest data from the Global Carbon Budget. Emissions rose 1.6% in 2017 after a temporary slowdown from 2014 to 2016, according to the Global Carbon Project. This year’s publication included contributions from 76 scientists from 53 research institutions, including from the World Climate Research Programme community.
